如何将位图保存到android库 [英] how to save bitmap to android gallery

问题描述

不幸的是，我发现的解决方案在Android 5.1.1上无效。
我有一个名为source的位图。我需要将它直接保存到我手机的图库中。我的清单包含< uses-permission android：name =android.permission.WRITE_EXTERNAL_STORAGE/>
你能给我一个工作方法吗？

unfortunately the solutions I've found didn't work on android 5.1.1. I have a bitmap called source. I need to save it directly to my phone's gallery. My manifest contains <uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" /> Can you give me a working method to do this?

推荐答案

使用这一个：

private void saveImage(Bitmap finalBitmap, String image_name) {

        String root = Environment.getExternalStorageDirectory().toString();
        File myDir = new File(root);
        myDir.mkdirs();
        String fname = "Image-" + image_name+ ".jpg";
        File file = new File(myDir, fname);
        if (file.exists()) file.delete();
        Log.i("LOAD", root + fname);
        try {
            FileOutputStream out = new FileOutputStream(file);
            finalBitmap.compress(Bitmap.CompressFormat.JPEG, 90, out);
            out.flush();
            out.close();
        } catch (Exception e) {
            e.printStackTrace();
        }
    }
